Modelling atmospheric transport persistent organic pollutants in Northern Hemisphere with a 3-D dynamical model
A first medium term monitoring of atmospheric transport and distribution for persistent organic pollutants (POPs) in Bjørnøya (Bear island) air samples has been performed in the period between week 51/1999 and week 28/2003. A total of 50 single compounds consisting of polychlorinated biphenyls (33 c...
